Add this to your maybe calendar – 9 to 5 Mac is reporting that both US and overseas Apple Stores have a scheduled “overnight” on July 24th, leading the news site to speculate on the release of OS X 10.8, Mountain Lion, for the following day.

One of the things Apple really gets right is the streamlined names. Other companies add a bunch of confusing prefixes and suffixes to each incremental product change, but with Apple a MacBook Pro is simply called a MacBook Pro, and not a MacBook Pro 15XRCT. It cuts down on the confusion for some of us simpletons.

So if that’s the case, you might be wondering: what the heck is all this talk of the iPhone 4S and iPhone 5? Are they the same device? If not, how are they different from each other? What does it all mean?

Well, it’s not as confusing as you think. Here’s the scoop on what all this talk about the iPhone 5 and iPhone 4S is really about.

One of the big questions everyone’s asking about the iPhone at the moment is whether or not a fifth generation device will launch this summer. According to a new report from Korean site ETNews.co.kr, Apple is planning to release the iPhone 5 during the 4th week of June, with Korean carriers SK Telecom and KT among the first providers to offer the device:

iPhone 5, the next model of iPhone 4, will be released on the coming 4th week of June. In the midst of the iPhone 5 postponement rumors, Apple has confirmed that iPhone 5 will be released as planned and it will be released simultaneously in Korea through SK Telecom and KT.
